Shrink Discs RLK 608 two-part design highest torque capacity Features • Highest torque capacity • Transmissible torque of 330 Nm up to 113 500 Nm • Easy, quick assembly by tightening clamping screws without a torque wrench • Distance-controlled assembly ensures guaranteed transmissible torques • Enclosed design, therefore impervious to dirt • True running even at high speeds • Centres the hollow shaft or hub to the shaft • For hollow shafts or hubs with outer diameters of 30 mm up to 190 mm 12-1 Application example Backlash free connection of a hollow-shaft gearbox to a machine shaft with a Shrink Disc RLK 608. The backlash free connection reduces the risk of fretting corrosion. As a result, the connection can be easily disassembled even after long periods of operation. Transmissible torques and axial forces The transmissible torques or axial forces listed on the following three pages are subject to the following tolerances, surface characteristics and material requirements. Please contact us in the case of deviations. Tolerances dw Hollow shaft bore ≤ > ISO mm mm 18 30 30 50 50 80 H7 80 120 120 160 160 165 H7 Other fits may be selected, provided the joint clearance between the shaft and the hollow shaft remains within the indicated ranges. Surfaces Average surface roughness at the contact surfaces between the shaft and the hollow shaft Rz = 10 … 25 µm. Materials The following apply to the shaft and the hollow shaft: • Yield strength Re ≥ 360 N/mm2 • E-module ca. 206 kN/mm2 Installation Please request our installation and operating instructions for Shrink Discs RLK 608. 12 Simultaneous transmission of torque and axial force The transmissible torques M which are shown in the tables apply for axial forces F = 0 kN and conversely, the indicated axial forces F apply to torques M = 0 Nm. If torque and axial force are to be t ransmitted s imultaneously, the transmissible torque and the transmissible axial force are reduced. Please refer to the technical points on page 35.
